Development of the sheet-pile foundation; A new seismic resistant foundation

摘要

The authors have proposed the sheet-pile foundation (SPF, hereafter) as a new foundation type. This foundation has advantages as follows; 1) Wider applicability to various soil conditions than the shallow foundations, 2) Minor impact to the environment with construction work, 3) More economical than the pile foundations in terms of cost. In this paper, seismic tests conducted to investigate the fundamental characteristics of the sheet-pile foundation during the earthquake for the development of the design method are presented.
